Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	1. Nature of Business Spire Global, Inc. (“Spire” or the “Company”), founded in August 2012, is a global provider of space-based data and analytics that offers its customers unique datasets and insights about earth from the ultimate vantage point. The Company collects this space-based data through its proprietary constellation of multi-purpose nanosatellites. By designing, manufacturing, integrating and operating its own satellites and ground stations, the Company has unique end-to-end control and ownership over its entire system. The Company offers the following three data solutions to customers: Maritime, Aviation and Weather. As a fourth solution, the Company is providing “space-as-a-service” through its Space Services solution. The Company is headquartered in Vienna, Virginia and has several wholly owned operating subsidiaries in the United States, United Kingdom, Luxembourg, Singapore, Australia, Germany, and Canada. On August 16, 2021, Spire Global Subsidiary, Inc. (formerly known as Spire Global, Inc.) (“Legacy Spire”) closed its previously announced merger with NavSight Holdings, Inc. (“NavSight”), a special purpose acquisition company. As a result, Legacy Spire continued as the surviving corporation and a wholly owned subsidiary of NavSight (the “Merger,” and such consummation, the “Closing”). NavSight then changed its name to Spire Global, Inc. and Legacy Spire changed its name to Spire Global Subsidiary, Inc. On September 14, 2022, the Company entered into an Equity Distribution Agreement (the “Equity Distribution Agreement”) with Canaccord Genuity LLC, as sales agent (the “Agent”). In accordance with the terms of the Equity Distribution Agreement, the Company may offer and sell its Class A common stock, having an aggregate offering price of up to $ 85,000 from time to time through the Agent pursuant to a registration statement on Form S-3, which became effective on September 26, 2022. Under the Equity Distribution Agreement, the Company sold (i) 2,166,389 shares of its Class A common stock during the year ended December 31, 2023 for gross proceeds of $ 8,235 and (ii) no shares during the three months ended March 31, 2024. On March 24, 2023, the Company, was notified by the New York Stock Exchange (“NYSE”) that the Company was not in compliance with Rule 802.01C of the NYSE’s Listed Company Manual (“Rule 802.01C”) relating to the minimum average closing price of the Company’s Class A common stock, par value of $ 0.0001 per share, required over a consecutive 30 trading-day period. On August 31, 2023, the Company effected a reverse stock split at a ratio of 1-for-8 (the “Reverse Stock Split”) of its common stock. In connection with the Reverse Stock Split, every eight shares of the Company’s Class A and Class B common stock issued and outstanding as of the effective date were automatically combined into one share of Class A or Class B common stock, as applicable. On September 25, 2023, the Company received formal notice from the NYSE that the Company had regained compliance with Rule 802.01C. On February 4, 2024, the Company and Signal Ocean Ltd (“Signal Ocean”) entered into a securities purchase agreement (the “SPA”) for the issuance and sale of 833,333 shares of the Company’s Class A common stock to Signal Ocean at a price of $ 12.00 per share (the “Private Placement”). The Private Placement closed on February 8, 2024, resulting in gross proceeds to the Company of $ 10.0 million. On March 21, 2024, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with institutional investors (the “Investors”), pursuant to which the Company issued and sold in a registered direct offering (the “Offering”), (i) an aggregate of 2,142,858 shares of Class A common stock and (ii) warrants exercisable for an aggregate of 2,142,858 shares of Class A common stock ("Securities Purchase Agreement Warrants") to the Investors. Each share of Class A common stock and accompanying Securities Purchase Agreement Warrant to purchase one share of Class A common stock was sold at an offering price of $ 14.00 . The aggregate gross proceeds to the Company from the Offering totaled $ 30,000 before deducting the placement agent’s fees and related offering expenses. The Securities Purchase Agreement Warrants have an exercise price equal to $ 14.50 per share of Class A common stock, are exercisable for a term beginning on March 25, 2024 and will expire on July 3, 2024. On March 21, 2024, the Company entered into a placement agency agreement (the “Placement Agency Agreement”) with Alliance Global Partners (“A.G.P” or the “Placement Agent”), pursuant to which the Company engaged A.G.P as the exclusive placement agent in connection with the Offering. The Company paid A.G.P a cash fee equal to 6 % of the gross proceeds from the sale of shares and Securities Purchase Agreement Warrants to the Investors, or $ 1,800 , in March 2024. The Company agreed to pay a cash fee equal to 4 % of the gross exercise price paid in cash with respect to the exercise of the Securities Purchase Agreement Warrants. The par value of the common stock remains $ 0.001 per share after the Reverse Stock Split. All share and per share information has been retroactively adjusted to reflect the impact of the Reverse Stock Split for applicable periods presented.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The condensed consolidated financial statements and accompanying notes are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and regulations of the U.S. Securities and Exchange Commission (the "SEC") for interim financial reporting. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations applicable to interim financial reporting. The unaudited condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, contain all adjustments, consisting of normal recurring adjustments necessary for a fair statement of its financial position, results of operations and cash flows for the periods indicated. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included within the Company's Annual Report on Form 10-K for the year ended December 31, 2023. The information as of December 31, 2023 included on the condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. All intercompany accounts and transactions have been eliminated in consolidation. Results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2024. Reverse Stock Split For the three months ended, and as of, March 31, 2023, reported share amounts, including issued and outstanding shares, per share amounts, and reported issued and outstanding warrants and other securities convertible into common stock in these condensed consolidated financial statements and accompanying notes have been retroactively adjusted for the Reverse Stock Split by applying the Reverse Stock Split ratio. The number of authorized shares of common stock was not impacted by the Reverse Stock Split, and therefore has not been retroactively adjusted. Liquidity Risks and Uncertainties Since inception, the Company has been engaged in developing its product offerings, raising capital, and recruiting personnel. The Company’s operating plan may change as a result of many factors currently unknown and there can be no assurance that the current operating plan will be achieved in the time frame anticipated by the Company, and it may need to seek additional funds sooner than planned. If adequate funds are not available to the Company on a timely basis, it may be required to delay, limit, reduce, or terminate certain commercial efforts, or pursue merger or acquisition strategies, all of which could adversely affect the holdings or the rights of the Company’s stockholders. The Company has a history of operating losses and negative cash flows from operations since inception. During the three months ended March 31, 2024, net loss was $ 25,256 , cash used in operations was $ 7,345 and the Company received net proceeds of $ 9,825 from the Private Placement and $ 28,056 from the Offering. The Company held cash and cash equivalents of $ 51,985 , excluding restricted cash of $ 486 , and investment in short-term marketable securities of $ 12,003 as of March 31, 2024. The Company currently believes that it will meet its minimum liquidity covenant, as well as all other financial covenants under the Blue Torch Financing Agreement (as amended, and as defined below in Note 6), at each applicable measurement point over the period of at least one year from the issuance of the March 31, 2024 condensed consolidated financial statements, and that it will have sufficient working capital to operate for a period of at least one year from the issuance of the March 31, 2024 condensed consolidated financial statements, in each case based on the Company's current cash and cash equivalents balance and expected future financial results. The Company’s assessment of the period of time through which its financial resources will be adequate to support its operations and meet its financial covenants is a forward-looking statement and involves risks and uncertainties. The Company’s actual results could vary as a result of many factors, including its growth rate, subscription renewal activity, the timing and extent of spending to support its infrastructure and research and development efforts and the expansion of sales and marketing activities. The Company may in the future enter into arrangements to acquire or invest in complementary businesses, services, and technologies, including intellectual property rights. The Company has based its estimates on assumptions that may prove to be wrong, and it could use its available capital resources sooner than it currently expects. The Company may be required to seek additional equity or debt financing or seek waivers of or amendments to contractual obligations. Future liquidity and cash requirements will depend on numerous factors, including market penetration, the introduction of new products, and potential acquisitions of related businesses or technology. In the event that additional financing is required from outside sources, the Company may not be able to raise it on acceptable terms or at all. If the Company is unable to raise additional capital when desired, unable to meet the minimum liquidity covenant or other financial covenants under the Blue Torch Financing Agreement or if it cannot expand its operations or otherwise capitalize on its business opportunities because it lacks sufficient capital, its business, results of operations, and financial condition would be adversely affected. Macroeconomic and Geopolitical Over the past two years, the Company has been impacted by the macroeconomic environment, such as fluctuations in foreign currencies, increasing interest rates and geopolitical conflicts like the Russian invasion of Ukraine, Israel's war with Hamas and the increased tensions between China and the U.S.. The U.S. dollar exhibited a modest decrease in strength against the local functional currencies of our foreign subsidiaries for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. This had a marginal positive impact on our revenue, as about one-third of the Company's sales are conducted in foreign currencies. Conversely, it had a marginal unfavorable impact on our expenses, given that a majority of the Company's workforce resides in countries other than the United States. The macroeconomic environment has caused existing or potential customers to re-evaluate their decision to purchase the Company's offerings, at times resulting in additional customer discounts, extended payment terms, longer sales cycles, and a few contract cancellations. Increasing interest rates in the three months ended March 31, 2024 compared to the three months ended March 31, 2023 resulted in higher interest expenses, as the Company’s credit facility is based on a floating interest rate. The Russian invasion of Ukraine and the continued conflict created additional global sanctions, which at times caused scheduling shifts or launch cancellations by third-party satellite launch providers and negatively impacted the availability of launch windows and our constellation replenishment efforts. If any of these factors continue or worsen, and/or if new macroeconomic or geopolitical issues arise, the Company's results and financial condition could be further negatively impacted. The Company cannot predict the timing, strength, or duration of any economic slowdown, downturn, instability, or recovery, generally or within any particular industry or geography. Any downturn of the general economy or industries in which the Company operates would adversely affect its business, financial condition, and results of operations. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the dates of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Management’s significant estimates include assumptions in revenue recognition, allowance for credit losses, valuation of certain assets and liabilities acquired from the acquisition of exactEarth in November 2021 (the “Acquisition”), realizability of deferred income tax assets, and fair value of equity awards, contingent earnout liabilities and warrant liabilities. Actual results could differ from those estimates. Based on an evaluation of the lifespans of its in-service satellites and on current capabilities to extend the useful life of in-service satellites via software updates, the Company changed the estimated useful life of its capitalized satellites and related launch costs from three to four years for depreciation purposes. The Company determined it was appropriate to make this change beginning June 2023. The change in estimated useful life did not have a material impact for the three months ended March 31, 2024. In November 2023, the Company updated the estimated useful lives for 43 capitalized satellites and related launch costs based on updated de-orbit dates. This change represents a change in accounting estimate and the impact of the change was an increase in loss from continuing operations before income taxes of approximately $ 3,009 , or $ 0.14 per basic and diluted share for the three months ended March 31, 2024. Cash, Cash Equivalents, Marketable Securities and Restricted Cash The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash included in Other long-term assets, including restricted cash on the condensed consolidated balance sheets, represents amounts pledged as guarantees or collateral for financing arrangements and lease agreements, as contractually required. The Company invests in highly rated securities, with the primary objective of minimizing the potential risk of principal loss. The Company’s investment policy generally requires securities to be investment grade and limits the amount of credit exposure to any one issuer. The Company’s investments in marketable debt securities have been classified and accounted for as available-for-sale. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Unrealized gains and losses on marketable debt securities classified as available-for-sale are recognized in Accumulated other comprehensive loss. Interest on securities classified as available-for-sale is included in Interest income on the condensed consolidated statements of operations. The following table shows components of cash, cash equivalents, and restricted cash reported on the condensed consolidated balance sheets and in the condensed consolidated statements of cash flows as of the dates indicated: March 31, December 31, 2024 2023 Cash and cash equivalents $ 51,985 $ 29,144 Restricted cash included in Other long-term assets 486 497 $ 52,471 $ 29,641 Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents and restricted cash, marketable securities, and accounts receivable. The Company typically has cash accounts in excess of Federal Deposit Insurance Corporation insurance coverage limits. The Company has not experienced any losses on such accounts, and management believes that the Company’s risk of loss is remote. The Company has a concentration of contractual revenue arrangements with various government agencies. Entities under common control are reported as a single customer. As of March 31, 2024, the Company had one customer (Customer A noted below) that accounted for 16 % of the Company’s total accounts receivable. As of December 31, 2023, the Company did not have any customers that accounted for more than 10 % of the Company’s total accounts receivable. The following customers represented 10% or more of the Company’s total revenue for each of the following periods: Three Months Ended March 31, 2024 2023 Customer A * 11 % Customer B (1) 29 % 29 % * Revenue from this customer was less than 10 % of total revenue during the period. (1) Consists of multiple U.S. government agencies, of which two and one government agencies represented greater than 10 % of total revenue for the three months ended March 31, 2024 and 2023, respectively. Related Parties In conjunction with the Company's acquisition of exactEarth in November 2021, Myriota Pty Ltd ("Myriota"), an existing Spire customer, became a related party as a result of exactEarth's approximately 13 % ownership of Myriota at the time of acquisition. As of March 31, 2024, the Company had 11.5 % ownership of Myriota. As of March 31, 2024 and December 31, 2023, $ 1,876 and $ 2,216 , respectively, of in vestment in Myriota were included in Other long-term assets, including restricted cash on the condensed consolidated balance sheets. The Company accounts for this investment using the equity method of accounting. The Company's share of earnings or losses on the investment is recorded on a one month lag, due to the timing of receiving financial statements from Myriota, as a component of Other expense, net in the condensed consolidated statements of operations. The Company generated $ 121 and $ 203 in revenue from Myriota for the three months ended March 31, 2024 and 2023, respectively, and had $ 52 of accounts receivable from Myriota as of March 31, 2024 and had no accounts receivable from Myriota as of December 31, 2023. Accounting Pronouncements Recently Adopted In March 2023,the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-01, Leases – Common Control Arrangements (Topic 842), to improve the accounting for amortizing leasehold improvements associated with arrangements between entities under common control. The amendment requires that leasehold improvements be amortized by the lessee over the useful life of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset through a lease. Additionally, leasehold improvements should be accounted for as a transfer between entities under common control through an adjustment to equity when the lessee no longer controls the use of the underlying asset. The amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2023, with early adoption permitted. The adoption of ASU 2023-01 as of January 1, 2024 did not impact the Company’s condensed consolidated financial statements. In August 2023, the FASB issued ASU 2023-05, Business Combinations – Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement. The amendments in this ASU are intended to facilitate consistency in the application of accounting guidance upon the formation of entities qualifying as joint ventures ("JVs"). This ASU generally requires the use of business combinations accounting at the JV formation date, which would result in the contributed assets/liabilities being revalued to fair value and potentially result in the recognition of goodwill and other intangibles on the JV’s financial statements. However, this ASU does not alter the ongoing accounting for the JV’s operations. This guidance is effective for JVs with formation dates on or after January 1, 20 25. The adoption of ASU 2023-05 as of January 1, 2024 did not impact the Company’s condensed consolidated financial statements. Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, Segment Reporting - Improvements to Reportable Segment Disclosures (Topic 280), to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclosure multiple segment measures of profit or loss, provide new segment disclosure requirements for entities within a single reportable segment, and contain other disclosure requirements. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and will be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the ASU to determine its impact on the Company’s disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes - Improvements to Income Tax Disclosures (Topic 740), to further enhance income tax disclosures to enable investors to better assess how an entity’s operations, related tax risks, tax planning, and operational opportunities affect its tax rate and prospects for future cash flows. The improvements primarily relate to the disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The other amendments improve the effectiveness and comparability of disclosures by adding disclosures of pretax income (or loss) and income tax expense (or benefit) to be consistent with SEC regulations. The ASU is effective for public business entities for annual reporting periods beginning after December 15, 2024. Early adoption is permitted and should be applied prospectively or retrospectively. The Company is currently evaluating the ASU to determine its impact on the Company’s disclosures. In March 2024, the SEC adopted final rules under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors , which will require registrants to provide certain climate-related information in their annual reports and registration statements. The rules will require disclosure of material climate-related risks, how the board of directors and management oversee and manage such risks, and the actual and potential impact of such risks on the registrant. It will also require disclosure about material climate-related targets and goals, and the financial impact of severe weather events and other natural conditions in the notes to audited financial statements. The disclosures will be required at the earliest in reports for the year ended December 31, 2025 (or potentially later depending on the Company's filer status at the time). The Company is currently evaluating the impact on the Company's disclosures.

As of March 31, 2024, the scheduled principal payments of long-term debt was as follows: Years ending December 31, Remainder of 2024 $ — 2025 — 2026 118,387 2027 335 2028 335 Thereafter 4,069 Total debt payments 123,126 Blue Torch Credit Agreement On June 13, 2022, the Company, as borrower, and Spire Global Subsidiary, Inc. and Austin Satellite Design, LLC, as guarantors, entered into a financing agreement (the “Blue Torch Financing Agreement”) with Blue Torch Finance LLC, a Delaware limited liability company (“Blue Torch”), as administrative agent and collateral agent, and certain lenders (the “Lenders”). The Blue Torch Financing Agreement provides for, among other things, a term loan facility in an aggregate principal amount of up to $ 120,000 (the “Blue Torch Credit Facility”). A portion of the proceeds of the term loan was used to repay the Company’s then-existing $ 70,000 credit facility with FP Credit Partners, L.P., and the remainder of the proceeds of the term loan may be used for general corporate purposes. The Blue Torch Credit Facility is scheduled to mature on June 13, 2026. Subject to certain exceptions, prepayments of principal under the Blue Torch Credit Facility will be subject to early termination fees in the amount of 3.0%, 2.0% and 1.0% of the principal prepaid if prepayment occurs within the first, second and third years following the closing date, respectively, plus if prepayment would have occurred on or prior to the first anniversary of the closing date, a make-whole amount equal to the amount of interest that would have otherwise been payable through the maturity date of the Blue Torch Credit Facility. The $120,000 term loan was available and drawn at closing, of which $19,735 was placed in an escrow account by Blue Torch with such amount to be released upon the Company achieving certain metrics related to annualized recurring revenue and a total annualized recurring revenue leverage ratio. These metrics were achieved and the $19,735 was released from the escrow account and delivered to the Company in February 2023. The term loan accrues interest at a floating rate, to be based, at the Company's election, on either a reference rate or a 3-month Term Secured Overnight Financing Rate ("SOFR") (subject to a 1.0% floor), plus an interest rate margin of 7.0% for reference rate borrowings and 8.0% for 3-month Term SOFR borrowings, plus an incremental Term SOFR margin of 0.26161%. The Company elected the Term SOFR rate which was 13.5766 % as of March 31, 2024. Principal on the term loan is only payable at maturity and interest on the term loan is due and payable quarterly for Term SOFR borrowings. The Company is also required to pay other customary fees and costs in connection with the Blue Torch Credit Facility, including a commitment fee in an amount equal to $ 2,400 on the closing date, a $ 250 annual agency fee and an exit fee of $ 1,800 upon termination of the Blue Torch Financing Agreement. The Blue Torch Financing Agreement contains customary affirmative covenants and customary negative covenants limiting the Company's ability and the ability of its subsidiaries to, among other things, dispose of assets, undergo a change in control, merge or consolidate, make acquisitions, incur debt, incur liens, pay dividends, repurchase stock and make investments, in each case subject to certain exceptions. The Company must also comply with a maximum debt to annualized recurring revenue leverage ratio financial covenant tested monthly during the first two years of the Blue Torch Financing Agreement, a maximum debt to EBITDA leverage ratio financial covenant tested monthly during the third and fourth years of the Blue Torch Financing Agreement and a minimum liquidity financial covenant tested at all times. On September 27, 2023, the Company entered into the Waiver and Amendment No. 2 to Financing Agreement (the “Waiver and Amendment”) with Blue Torch and the Lenders, which amends the Blue Torch Financing Agreement to (a) waive an event of default under the Blue Torch Financing Agreement arising out of the total annualized recurring revenue leverage ratio being greater than the permitted ratio, (b) amend the financial covenants to provide covenant relief from the maximum debt to annualized recurring revenue leverage ratio and the maximum debt to EBITDA leverage ratio set forth in the Blue Torch Financing Agreement for future periods, and (c) provide for a second amendment exit fee. The second amendment exit fee is $ 1,800 (which is an amount equal to one and a half percent ( 1.50 %) of the aggregate outstanding principal balance of the term loans on the effective date of the Waiver and Amendment), bears interest from the date of the Waiver and Amendment at the Adjusted Term SOFR for a 3-month interest period plus the applicable margin under the Financing Agreement, and is payable by the Company in cash upon the termination of the Blue Torch Financing Agreement, either as a result of acceleration of the loans or at the final maturity date. The Waiver and Amendment required a repayment by the Company of $ 2,500 of the outstanding principal balance of the term loans and a prepayment premium of $ 50 , which were paid on October 2, 2023. The Waiver and Amendment also requires additional reporting if the Company’s liquidity level is less than $ 35,000 at any time during a month and revises the minimum liquidity covenant to require liquidity of at least $ 30,000 at all times, commencing on September 30, 2023, which in both cases represent a $ 5,000 incremental change from the original requirements. The Company was in compliance with all applicable financial covenants as of March 31, 2024. On June 13, 2022, in connection with the Blue Torch Financing Agreement, the Company issued warrants to Blue Torch, which were exercisable for an aggregate of 437,024 shares of the Company’s Class A common stock with a per share exercise price of $ 16.08 (the “2022 Blue Torch Warrants”). In addition, in connection with the closing of the financing, the Company paid Urgent Capital LLC, a Delaware limited liability company, a fee for introducing the Company to the Lenders, for the purpose of loan financing, in the amount equal to $ 600 in cash and a warrant to purchase 24,834 fully paid and non-assessable shares of the Company's Class A common stock with a per share exercise price of $ 16.88 (the “Urgent Warrants”). On September 27, 2023, in connection with the Waiver and Amendment, the Company and certain affiliates of Blue Torch amended and restated the 2022 Blue Torch Warrants to reduce the per share exercise price from $ 16.08 to $ 5.44 . The Company also concurrently issued new warrants to certain Blue Torch affiliates that are exercisable for an additional 597,082 shares of the Company’s Class A common stock at a per share exercise price of $ 5.44 (the “2023 Blue Torch Warrants" and together with the 2022 Blue Torch Warrants and the Urgent Warrants, the “Credit Agreement Warrants”). The Company evaluated the Credit Agreement Warrants and concluded that they do not meet the criteria to be classified within stockholders’ equity. The agreements governing the Credit Agreement Warrants include a provision that could result in a different settlement value for the Credit Agreement Warrants depending on their holder. Because the holder of an instrument is not an input into the pricing of a fixed-for-fixed option on the Company’s Class A common stock, the Credit Agreement Warrants are not considered to be indexed to the Company’s Class A common stock. As the Credit Agreement Warrants meet the definition of a derivative, the Company recorded these warrants as liabilities on the consolidated balance sheets at fair value (Note 8) based on the Black-Scholes model as of June 13, 2022 and September 27, 2023 with inputs that include the Company’s Class A common stock price in an actively traded market, making this fair value classified as a Level 2 financial instrument. The other significant assumptions used in the model are the exercise price, expected term, volatility, interest rate, and dividend yield. Subsequent changes in their respective fair values are recognized in the consolidated statements of operations at each reporting date. Changes in the fair value of the warrant liabilities will continue to be recognized until the warrants are exercised, expire, or qualify for equity classification. The Credit Agreement Warrants may be exercised on a cashless basis. The Credit Agreement Warrants are exercisable for a term beginning on the date of issuance and ending on the earlier to occur of ten years from the date of issuance or the consummation of certain of the Company's acquisitions as set forth in the Credit Agreement Warrants. The number of shares for which the Credit Agreement Warrants are exercisable and the associated exercise price are subject to certain proportional adjustments as set forth in the Credit Agreement Warrants. On April 8, 2024, the Company entered into Amendment No. 3 to Financing Agreement (the “Third Amendment”) with Blue Torch and the Lenders, which amends the Blue Torch Financing Agreement to (i) increase the maximum debt to EBITDA leverage ratio for the monthly periods ending June 30, 2024, July 31, 2024 and August 31, 2024, and to decrease the maximum permitted ratio thereafter, and (ii) amend the minimum liquidity covenant to require liquidity of at least $ 20,000 at all times, commencing on April 8, 2024, which represents a $ 10,000 decrease from the requirement in effect immediately prior to the effective date of the Third Amendment. On April 8, 2024, in accordance with the terms of the Third Amendment, the Company made a prepayment to Blue Torch of $ 10,000 in principal, plus an early termination fee of $ 200 . Government Loan In November 2021, the Company completed the Acquisition and assumed an interest free loan agreement wit h the Strategic Innovation Fund ("SIF") which was recorded at an amount equal to the proceeds received. Under this agreement and subsequent amendment, the Company was eligible to receive funding for certain expenditures incurred from February 13, 2018 to May 12, 2023, up to a maximum of $ 5,701 . As of March 31, 2024 and December 31, 2023, $ 5,017 and $ 5,128 , respectively, was included in long-term debt, non-current on the condensed consolidated balance sheets related to the SIF loan agreement. Any amount outstanding under this loan is repayable in 15 annual payments beginning February 28, 2026 and has a stated interest rate of zero.

Fair Value Disclosures [Abstract]
Fair Value Measurement	8. Fair Value Measurement The Company follows the guidance in Accounting Standards Codification (“ASC”) 820, “Fair Value Measurement” for its liabilities that are re-measured and reported at fair value at the end of each reporting period. The fair value of the Company’s common stock warrant liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Significant other observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3: Unobservable inputs reflecting management’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. The Company classifies financial instruments in Level 3 of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of inputs that are readily observable, either directly or indirectly. The Company’s assessment of a particular input to the fair value measurement requires management to make judgments and consider factors specific to the asset or liability. The fair value hierarchy requires the use of observable market data when available in determining fair value. The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each period. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present the Company’s fair value hierarchy for its financial instruments that are measured at fair value on a recurring basis. March 31, 2024 Level 1 Level 2 Level 3 Total Assets: Cash and cash equivalents: Money market funds $ 10,123 $ — $ — $ 10,123 $ 10,123 $ — $ — $ 10,123 Marketable securities: U.S. treasury bills and bonds $ 11,018 $ — $ — $ 11,018 Commercial paper — 985 — 985 $ 11,018 $ 985 $ — $ 12,003 Long-term liabilities: Credit Agreement Warrants $ — $ 10,672 $ — $ 10,672 Securities Purchase Agreement Warrants — 1,917 — $ 1,917 Contingent earnout liability — — 265 265 $ — $ 12,589 $ 265 $ 12,854 December 31, 2023 Level 1 Level 2 Level 3 Total Assets: Cash and cash equivalents: Money market funds $ 10,114 $ — $ — $ 10,114 $ 10,114 $ — $ — $ 10,114 Marketable securities: U.S. treasury bills and bonds $ 8,840 $ — $ — $ 8,840 Commercial paper — 1,395 — 1,395 U.S. government and agency securities — 1,491 — 1,491 $ 8,840 $ 2,886 $ — $ 11,726 Long-term liabilities: Credit Agreement Warrants $ — $ 5,988 $ — $ 5,988 Contingent earnout liability — — 220 220 $ — $ 5,988 $ 220 $ 6,208 Financial Assets The Company values its Level 1 assets, consisting of money market funds, and U.S. treasury bills and bonds, using quoted prices in active markets for identical instruments. Financial assets whose fair values that are measured on a recurring basis using Level 2 inputs consist of commercial paper, and U.S. government and agency securities. The Company measures the fair values of these assets with the help of a pricing service that either provides quoted market prices in active markets for identical or similar securities or uses observable inputs for their pricing without applying significant adjustments. Credit Agreement Warrants On June 13, 2022, in connection with the Blue Torch Financing Agreement, the Company issued the 2022 Blue Torch Warrants to Blue Torch, which were exercisable for an aggregate of 437,024 shares of the Company’s Class A common stock with a per share exercise price of $ 16.08 . Additionally, in connection with the closing of the financing, the Company issued the Urgent Warrants to Urgent Capital LLC for introducing the Company to the Lenders, which is exercisable for an aggregate of 24,834 shares of the Company's Class A common stock with a per share exercise price of $ 16.08 . On September 27, 2023, in connection with the Waiver and Amendment, the Company and certain affiliates of Blue Torch amended and restated the 2022 Blue Torch Warrants to reduce the per share exercise price from $ 16.08 to $ 5.44 . The Company also concurrently issued the 2023 Blue Torch Warrants to those affiliates that are exercisable for an additional 597,082 shares of the Company’s Class A common stock at a per share exercise price of $ 5.44 . The fair value of the Credit Agreement Warrants is estimated using the Black-Scholes model with inputs that include the Company’s Class A common stock price in an actively traded market, making this fair value classified as a Level 2 financial instrument. The other significant assumptions used in the model are the exercise price, expected term, volatility, interest rate, and expected dividend yield. The table below quantifies the significant inputs used for the Credit Agreement Warrants: March 31, December 31, 2024 2023 Fair value of the Company’s Class A common stock $ 12.00 $ 7.82 Exercise price $ 5.44 - 16.08 $ 5.44 - 16.08 Risk-free interest rate 4.20 % 3.88 % Expected volatility factor 68.8 % 55.0 % Expected dividend yield — % — % Remaining contractual term (in years) 8.2 - 9.5 8.5 - 9.7 Securities Purchase Agreement Warrants On March 21, 2024, the Company entered into the Purchase Agreement with the Investors, pursuant to which the Company issued and sold in the Offering, (i) an aggregate of 2,142,858 shares of Class A common stock and (ii) Securities Purchase Agreement Warrants exercisable for an aggregate of 2,142,858 shares of Class A common stock to the Investors. Each share of Class A common stock and accompanying Securities Purchase Agreement Warrant to purchase one share of Class A common stock was sold at an offering price of $ 14.00 . The aggregate gross proceeds to the Company from the Offering totaled $ 30,000 before deducting the placement agent’s fees and related offering expenses. The Securities Purchase Agreement Warrants have an exercise price equal to $ 14.50 per share of Class A common stock, are exercisable for a term beginning on March 25, 2024 and will expire on July 3, 2024. The fair value of the Securities Purchase Agreement Warrants is estimated using the Black-Scholes model with inputs that include the Company’s Class A common stock price in an actively traded market, making this fair value classified as a Level 2 financial instrument. The other significant assumptions used in the model are the exercise price, expected term, volatility, interest rate, and expected dividend yield. The table below quantifies the significant inputs used for the Securities Purchase Agreement Warrants: March 31, 2024 Fair value of the Company’s Class A common stock $ 12.00 Exercise price $ 14.50 Risk-free interest rate 5.46 % Expected volatility factor 68.8 % Expected dividend yield — % Remaining contractual term (in years) 0.3 Contingent Earnout Liability In connection with the Merger, eligible Spire equity holders are entitled to receive additional shares of the Company's Class A common stock upon the achievement of certain earnout triggering events. The estimated fair value of the contingent earnout liability is determined using a Monte Carlo simulation using a distribution of potential outcomes on a monthly basis over the earnout period, which is a period up to five years post-closing of the Merger, prioritizing the most reliable information available, making this fair value classified as a Level 3 liability. The assumptions utilized in the calculation are based on the achievement of certain stock price milestones, including the current price of the Company’s Class A common stock, expected volatility, risk-free interest rate, expected term and expected dividend yield. The table below quantifies the significant inputs used for the contingent earnout liability: March 31, December 31, 2024 2023 Fair value of the Company’s Class A common stock $ 12.00 $ 7.82 Risk-free interest rate 4.52 % 4.09 % Expected volatility factor 68.8 % 55.0 % Earnout expiration date August 16, 2026 August 16, 2026 The following table presents a summary of the changes in the fair value of the Company’s Level 3 financial instruments that are measured at fair value on a recurring basis: Contingent Fair value as of December 31, 2023 220 Change in fair value of contingent earnout liability 45 Fair value as of March 31, 2024 $ 265 Cash and Cash Equivalents and Marketable Securities The following tables summarize the Company's cash, cash equivalents and available-for-sale securities by significant marketable securities category: March 31, 2024 Amortized Cost Unrealized Gains Unrealized Losses Fair Value Cash and cash equivalents: Cash $ 41,862 $ — $ — $ 41,862 Cash equivalents: Money market funds 10,123 — — 10,123 $ 51,985 $ — $ — $ 51,985 Marketable Securities: U.S. treasury bills and bonds $ 11,018 $ — $ — $ 11,018 Commercial paper 986 — ( 1 ) 985 $ 12,004 $ — $ ( 1 ) $ 12,003 December 31, 2023 Amortized Cost Unrealized Gains Unrealized Losses Fair Value Cash and cash equivalents: Cash $ 19,030 $ — $ — $ 19,030 Cash equivalents: Money market funds 10,114 — — 10,114 $ 29,144 $ — $ — $ 29,144 Marketable Securities: U.S. treasury bills and bonds $ 8,838 $ 2 $ — $ 8,840 Commercial paper 1,395 — — 1,395 U.S. government and agency securities 1,492 — ( 1 ) 1,491 $ 11,725 $ 2 $ ( 1 ) $ 11,726 The following table represents amortized cost and estimated fair value of marketable securities, by contractual maturity: March 31, 2024 Amortized Cost Fair Value Due in one year or less $ 12,004 $ 12,003 In accordance with the Company's investment policy, investments are placed in investment grade securities with high credit quality issuers, and generally limit the amount of credit exposure to any one issuer. The Company evaluates securities for impairment at the end of each reporting period. The Company did not record any impairment charges related to its available-for-sale securities during the three months ended March 31, 2024 and 2023.

Net Loss per Share	11. Net Loss per Share The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders: Three Months Ended March 31, 2024 2023 Numerator: Net loss $ ( 25,256 ) $ ( 17,673 ) Denominator: Weighted-average shares used in computing basic and diluted 21,813,045 18,096,363 Basic and diluted net loss per share $ ( 1.16 ) $ ( 0.98 ) The Company has two classes of common stock, Class A and Class B. Class B common stock has no economic rights, and therefore has been excluded from the computation of basic and diluted net loss per share. Potentially dilutive securities have been excluded from the computation of diluted net loss per share as the effect would reduce net loss per share. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potential shares of Class A common stock, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share for the three months ended March 31, 2024 and 2023, because including them would have had an anti-dilutive effect: Three Months Ended March 31, 2024 2023 Stock options and 2021 ESPP 2,028,412 2,422,401 RSUs 2,763,462 1,442,755 Securities Purchase Agreement Warrants 2,142,858 — Credit Agreement Warrants 1,058,940 461,860 7,993,672 4,327,016

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements and accompanying notes are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and regulations of the U.S. Securities and Exchange Commission (the "SEC") for interim financial reporting. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations applicable to interim financial reporting. The unaudited condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, contain all adjustments, consisting of normal recurring adjustments necessary for a fair statement of its financial position, results of operations and cash flows for the periods indicated. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included within the Company's Annual Report on Form 10-K for the year ended December 31, 2023. The information as of December 31, 2023 included on the condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. All intercompany accounts and transactions have been eliminated in consolidation. Results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2024. Reverse Stock Split For the three months ended, and as of, March 31, 2023, reported share amounts, including issued and outstanding shares, per share amounts, and reported issued and outstanding warrants and other securities convertible into common stock in these condensed consolidated financial statements and accompanying notes have been retroactively adjusted for the Reverse Stock Split by applying the Reverse Stock Split ratio. The number of authorized shares of common stock was not impacted by the Reverse Stock Split, and therefore has not been retroactively adjusted.
Liquidity Risks and Uncertainties	Liquidity Risks and Uncertainties Since inception, the Company has been engaged in developing its product offerings, raising capital, and recruiting personnel. The Company’s operating plan may change as a result of many factors currently unknown and there can be no assurance that the current operating plan will be achieved in the time frame anticipated by the Company, and it may need to seek additional funds sooner than planned. If adequate funds are not available to the Company on a timely basis, it may be required to delay, limit, reduce, or terminate certain commercial efforts, or pursue merger or acquisition strategies, all of which could adversely affect the holdings or the rights of the Company’s stockholders. The Company has a history of operating losses and negative cash flows from operations since inception. During the three months ended March 31, 2024, net loss was $ 25,256 , cash used in operations was $ 7,345 and the Company received net proceeds of $ 9,825 from the Private Placement and $ 28,056 from the Offering. The Company held cash and cash equivalents of $ 51,985 , excluding restricted cash of $ 486 , and investment in short-term marketable securities of $ 12,003 as of March 31, 2024. The Company currently believes that it will meet its minimum liquidity covenant, as well as all other financial covenants under the Blue Torch Financing Agreement (as amended, and as defined below in Note 6), at each applicable measurement point over the period of at least one year from the issuance of the March 31, 2024 condensed consolidated financial statements, and that it will have sufficient working capital to operate for a period of at least one year from the issuance of the March 31, 2024 condensed consolidated financial statements, in each case based on the Company's current cash and cash equivalents balance and expected future financial results. The Company’s assessment of the period of time through which its financial resources will be adequate to support its operations and meet its financial covenants is a forward-looking statement and involves risks and uncertainties. The Company’s actual results could vary as a result of many factors, including its growth rate, subscription renewal activity, the timing and extent of spending to support its infrastructure and research and development efforts and the expansion of sales and marketing activities. The Company may in the future enter into arrangements to acquire or invest in complementary businesses, services, and technologies, including intellectual property rights. The Company has based its estimates on assumptions that may prove to be wrong, and it could use its available capital resources sooner than it currently expects. The Company may be required to seek additional equity or debt financing or seek waivers of or amendments to contractual obligations. Future liquidity and cash requirements will depend on numerous factors, including market penetration, the introduction of new products, and potential acquisitions of related businesses or technology. In the event that additional financing is required from outside sources, the Company may not be able to raise it on acceptable terms or at all. If the Company is unable to raise additional capital when desired, unable to meet the minimum liquidity covenant or other financial covenants under the Blue Torch Financing Agreement or if it cannot expand its operations or otherwise capitalize on its business opportunities because it lacks sufficient capital, its business, results of operations, and financial condition would be adversely affected.
Macroeconomic and Geopolitical	Macroeconomic and Geopolitical Over the past two years, the Company has been impacted by the macroeconomic environment, such as fluctuations in foreign currencies, increasing interest rates and geopolitical conflicts like the Russian invasion of Ukraine, Israel's war with Hamas and the increased tensions between China and the U.S.. The U.S. dollar exhibited a modest decrease in strength against the local functional currencies of our foreign subsidiaries for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. This had a marginal positive impact on our revenue, as about one-third of the Company's sales are conducted in foreign currencies. Conversely, it had a marginal unfavorable impact on our expenses, given that a majority of the Company's workforce resides in countries other than the United States. The macroeconomic environment has caused existing or potential customers to re-evaluate their decision to purchase the Company's offerings, at times resulting in additional customer discounts, extended payment terms, longer sales cycles, and a few contract cancellations. Increasing interest rates in the three months ended March 31, 2024 compared to the three months ended March 31, 2023 resulted in higher interest expenses, as the Company’s credit facility is based on a floating interest rate. The Russian invasion of Ukraine and the continued conflict created additional global sanctions, which at times caused scheduling shifts or launch cancellations by third-party satellite launch providers and negatively impacted the availability of launch windows and our constellation replenishment efforts. If any of these factors continue or worsen, and/or if new macroeconomic or geopolitical issues arise, the Company's results and financial condition could be further negatively impacted. The Company cannot predict the timing, strength, or duration of any economic slowdown, downturn, instability, or recovery, generally or within any particular industry or geography. Any downturn of the general economy or industries in which the Company operates would adversely affect its business, financial condition, and results of operations.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the dates of the condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Management’s significant estimates include assumptions in revenue recognition, allowance for credit losses, valuation of certain assets and liabilities acquired from the acquisition of exactEarth in November 2021 (the “Acquisition”), realizability of deferred income tax assets, and fair value of equity awards, contingent earnout liabilities and warrant liabilities. Actual results could differ from those estimates. Based on an evaluation of the lifespans of its in-service satellites and on current capabilities to extend the useful life of in-service satellites via software updates, the Company changed the estimated useful life of its capitalized satellites and related launch costs from three to four years for depreciation purposes. The Company determined it was appropriate to make this change beginning June 2023. The change in estimated useful life did not have a material impact for the three months ended March 31, 2024. In November 2023, the Company updated the estimated useful lives for 43 capitalized satellites and related launch costs based on updated de-orbit dates. This change represents a change in accounting estimate and the impact of the change was an increase in loss from continuing operations before income taxes of approximately $ 3,009 , or $ 0.14 per basic and diluted share for the three months ended March 31, 2024.
Cash, Cash Equivalents, Marketable Securities and Restricted Cash	Cash, Cash Equivalents, Marketable Securities and Restricted Cash The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash included in Other long-term assets, including restricted cash on the condensed consolidated balance sheets, represents amounts pledged as guarantees or collateral for financing arrangements and lease agreements, as contractually required. The Company invests in highly rated securities, with the primary objective of minimizing the potential risk of principal loss. The Company’s investment policy generally requires securities to be investment grade and limits the amount of credit exposure to any one issuer. The Company’s investments in marketable debt securities have been classified and accounted for as available-for-sale. The Company classifies its marketable debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Unrealized gains and losses on marketable debt securities classified as available-for-sale are recognized in Accumulated other comprehensive loss. Interest on securities classified as available-for-sale is included in Interest income on the condensed consolidated statements of operations. The following table shows components of cash, cash equivalents, and restricted cash reported on the condensed consolidated balance sheets and in the condensed consolidated statements of cash flows as of the dates indicated: March 31, December 31, 2024 2023 Cash and cash equivalents $ 51,985 $ 29,144 Restricted cash included in Other long-term assets 486 497 $ 52,471 $ 29,641
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents and restricted cash, marketable securities, and accounts receivable. The Company typically has cash accounts in excess of Federal Deposit Insurance Corporation insurance coverage limits. The Company has not experienced any losses on such accounts, and management believes that the Company’s risk of loss is remote. The Company has a concentration of contractual revenue arrangements with various government agencies. Entities under common control are reported as a single customer. As of March 31, 2024, the Company had one customer (Customer A noted below) that accounted for 16 % of the Company’s total accounts receivable. As of December 31, 2023, the Company did not have any customers that accounted for more than 10 % of the Company’s total accounts receivable. The following customers represented 10% or more of the Company’s total revenue for each of the following periods: Three Months Ended March 31, 2024 2023 Customer A * 11 % Customer B (1) 29 % 29 % * Revenue from this customer was less than 10 % of total revenue during the period. (1) Consists of multiple U.S. government agencies, of which two and one government agencies represented greater than 10 % of total revenue for the three months ended March 31, 2024 and 2023, respectively.
Related Parties	Related Parties In conjunction with the Company's acquisition of exactEarth in November 2021, Myriota Pty Ltd ("Myriota"), an existing Spire customer, became a related party as a result of exactEarth's approximately 13 % ownership of Myriota at the time of acquisition. As of March 31, 2024, the Company had 11.5 % ownership of Myriota. As of March 31, 2024 and December 31, 2023, $ 1,876 and $ 2,216 , respectively, of in vestment in Myriota were included in Other long-term assets, including restricted cash on the condensed consolidated balance sheets. The Company accounts for this investment using the equity method of accounting. The Company's share of earnings or losses on the investment is recorded on a one month lag, due to the timing of receiving financial statements from Myriota, as a component of Other expense, net in the condensed consolidated statements of operations. The Company generated $ 121 and $ 203 in revenue from Myriota for the three months ended March 31, 2024 and 2023, respectively, and had $ 52 of accounts receivable from Myriota as of March 31, 2024 and had no accounts receivable from Myriota as of December 31, 2023.
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted In March 2023,the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-01, Leases – Common Control Arrangements (Topic 842), to improve the accounting for amortizing leasehold improvements associated with arrangements between entities under common control. The amendment requires that leasehold improvements be amortized by the lessee over the useful life of the leasehold improvements to the common control group (regardless of the lease term) as long as the lessee controls the use of the underlying asset through a lease. Additionally, leasehold improvements should be accounted for as a transfer between entities under common control through an adjustment to equity when the lessee no longer controls the use of the underlying asset. The amendments in this update are effective for financial statements issued for annual periods beginning after December 15, 2023, with early adoption permitted. The adoption of ASU 2023-01 as of January 1, 2024 did not impact the Company’s condensed consolidated financial statements. In August 2023, the FASB issued ASU 2023-05, Business Combinations – Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement. The amendments in this ASU are intended to facilitate consistency in the application of accounting guidance upon the formation of entities qualifying as joint ventures ("JVs"). This ASU generally requires the use of business combinations accounting at the JV formation date, which would result in the contributed assets/liabilities being revalued to fair value and potentially result in the recognition of goodwill and other intangibles on the JV’s financial statements. However, this ASU does not alter the ongoing accounting for the JV’s operations. This guidance is effective for JVs with formation dates on or after January 1, 20 25. The adoption of ASU 2023-05 as of January 1, 2024 did not impact the Company’s condensed consolidated financial statements.
Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU 2023-07, Segment Reporting - Improvements to Reportable Segment Disclosures (Topic 280), to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclosure multiple segment measures of profit or loss, provide new segment disclosure requirements for entities within a single reportable segment, and contain other disclosure requirements. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and will be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the ASU to determine its impact on the Company’s disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes - Improvements to Income Tax Disclosures (Topic 740), to further enhance income tax disclosures to enable investors to better assess how an entity’s operations, related tax risks, tax planning, and operational opportunities affect its tax rate and prospects for future cash flows. The improvements primarily relate to the disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The other amendments improve the effectiveness and comparability of disclosures by adding disclosures of pretax income (or loss) and income tax expense (or benefit) to be consistent with SEC regulations. The ASU is effective for public business entities for annual reporting periods beginning after December 15, 2024. Early adoption is permitted and should be applied prospectively or retrospectively. The Company is currently evaluating the ASU to determine its impact on the Company’s disclosures. In March 2024, the SEC adopted final rules under SEC Release No. 33-11275, The Enhancement and Standardization of Climate-Related Disclosures for Investors , which will require registrants to provide certain climate-related information in their annual reports and registration statements. The rules will require disclosure of material climate-related risks, how the board of directors and management oversee and manage such risks, and the actual and potential impact of such risks on the registrant. It will also require disclosure about material climate-related targets and goals, and the financial impact of severe weather events and other natural conditions in the notes to audited financial statements. The disclosures will be required at the earliest in reports for the year ended December 31, 2025 (or potentially later depending on the Company's filer status at the time). The Company is currently evaluating the impact on the Company's disclosures.
